TDX Series – Direct Vent
The TDX Series achieves its high efficiencies by re-circulating the flue gases through the boiler three times. Most other residential boilers are designed for only one or two passes through the boilers. With our three-pass design, the flue gases do not immediately exit through the chimney, but remain in the boiler longer for more efficient operation.
The TDX Series incorporates a specially designed water coil, which provides an abundant and equally efficient supply of domestic hot water.
- FIRING RATE 0.90 to 1.25 GPH – Allows the installer to size the boiler more closely to the home heating needs for greater efficiency. The lowest firing rate, 0.90-95,000 BTU, is necessary for many well insulated homes where the heat loss is minimal.
- PUMP PRESSURE – The TDX-Series operates at 140 PSI pump pressure for better fuel atomization, thereby having the ability to tolerate fuel oil with heavy ends.
- IGNITION SYSTEM – The TDX-Series is standard with a state-of-the-art, solid state ignition system, making it more tolerant to low voltage or voltage fluctuations.
- ELECTRONIC DELAY with Solenoid Valve “clean-cut” Fuel Pump
WATER CONTENT – 29.3 gallons
- EFFICIENCIES UP TO 87% AFUE – The unique tube design of the S-Series boiler heat exchanger slows the flue gases, allowing for more effective heat transfer without the need for extreme baffling often seen in other vertical tube boilers.
- STANDARD FEATURES- The following built-in features found in all Thermo-Dynamics boilers increase the longevity of the boiler and make the unit easier to service, ensuring maximum efficiency and performance for the life of the boiler.
- BUILT-IN “AIR SCOOP” – purges air from the system providing a quiet, trouble free hot water heating system without the use of external devices.
- EXTENDED FLANGE COIL – is away from the boiler for easy accessibility. The use of ribbed neck carriage bolts eliminates the problems encountered when a weld stud is broken during servicing. The large coil plate allows for a greater gasket sealing area.
- EASY CLEANING – and maintenance accessibility to combustion areas and the open tubes make it easy for the service technician to thoroughly clean the boiler. No tight, pin-type passage ways with “hidden nooks and crannies”, making a thorough cleaning impossible. A well-maintained boiler continues to perform at higher efficiency and is less likely to develop service problems.
Standard Features
- EFFICIENT, SENSIBLE AND DEPENDABLE – High efficiency of 87%, recirculating triple pass design and includes an advanced boiler control for increased operating efficiency and low water cut-off
- EFFICIENT – Achieves its high efficiencies by re-circulating the flue gases through the boiler three times. With our three-pass design the flue gases do not immediately exit through the chimney, but remain in the boiler longer for more efficient operation.
- VENTING – The TDX can be vented by either a standard chimney or direct-vent with an optional DV kit. Such application would be ideal for new home without a chimney, older homes with chimneys not up to code or electric to oil conversions.
- Serviceability – designed with a heating professional in mind. A unique front jacket panel designed for easy removal allows convenient access to a one piece, swing out door.
